Title: Innovations by Dennis A. Chojnacki: Revolutionizing Combustion Technology
Introduction
Dennis A. Chojnacki is an accomplished inventor based in Roselle, Illinois, known for his innovative contributions to combustion technology. With a total of two patents to his name, Chojnacki is recognized for developing advanced methods and apparatuses that enhance combustion efficiency and reduce harmful emissions.
Latest Patents
Chojnacki's most recent patents include a groundbreaking method and apparatus for combustion, where a pressurized, preheated liquid fuel is atomized and flash vaporized. This process creates a mixture of fuel vapor and liquid droplets, which is then combined with a primary combustion oxidant. The fuel/oxidant mixture is injected into a primary combustion chamber, resulting in a partially combusted secondary gaseous fuel rich in hydrogen and carbon oxides. This secondary gaseous fuel is further mixed with a secondary combustion oxidant and injected into a second combustion chamber for complete combustion, ultimately producing flue gas with minimal NO emissions.
Additionally, he has patented a firetube boiler furnace featuring two combustion sections and an intermediate tubular heat transfer section. This design allows for separate in-line combustion chambers—one for fuel-rich primary combustion and the other for fuel-lean secondary combustion—ensuring adequate cooling of combustion products. The innovative setup contributes to maintaining NO formation below 5 parts per million by volume at 3% O.
